4 Claims.

My present invention relates to the art of embalming corpses and more particularly to apparatus for injecting the embalming fluid under pressure into the circulatory canals of the body, and it has for its object to provide an improved tank or reservoir for the uid which will be particularly eflicient and convenient for use by morticians in using the gravity system of infusion whether in private homes or in their own better equipped operating rooms. The improvements are directed in part toward the means whereby the reservoir is lled and stoppered and the means whereby air is let in to take the place of the liquid drained out, all with a view to removing the possibility of even the slightest amount of the embalming uid, which has such a permeating and objectionable odor from spilling out. To these and other ends, the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of this specification.

In the drawings:

Fig. 1 is an elevation of a hydrostatic infusion apparatus in operating position, the same being constructed in accordance with and illustrating one embodiment of my invention;

- Fig. 2 is an enlarged fragmentary bottom plan view thereof;

y Fig. 3 is a fragmentary similarly enlarged side view of the stopper taken at an angle of 90 from the showing of Fig. 1;

Fig. 4 is a central vertical section, but with the drain tube and part of the air intake tube 5 shown in elevation; and

Fig. 5 is another fragmentary vertical central section taken completely through the air intake tube in a plane lying at 90 to that of the section of Fig. 4.

Similar reference numerals throughout the several views indicate the same parts.

Referring more particularly to the drawings, the device, in the embodiment shown and in the operative position illustrated throughout the views, is in the form of an inverted heavy glass bottle 1 which is preferably provided with a skeletonized metallic reenforcing case or frame 2.v What corresponds to the bottom 3 of the bottle but is the top of the apparatus in its said operative position and will be so referred to hereinafter is tted in connection with this frame with a cross bar 4, to which is attached a hook 5, by means of which the device may be suspended in any suitable manner at the proper height to 55 give the desired hydrostatic pressure. In my copending application, Serial No. 635,444, filed September 29, 1932, I describe and claim a" cable and bracket support useful in this connection-and the engaging portion of which is indicated at 6 in Fig.1. f

The neck -7 of the bottle at the bottom hasa tapered throat, as showninFigs. 4r and' 5; fin which is wedged a reasonably soft rubber gasket and bushing 8; Wedge'd into` this infturn is a tapered 'hollow metallick stopper 9V consisting of a thimble-like body anda cap piece-10 joined thereto toform' a small cavity 11-that-consti tutes a trap to catch the leakage hereinafterexplained.l Y Extending upwardly through theV stopper 9' are two pipes 12 and 13 arranged side by side ter.- lminating exteriorlyv at the bottom in' hose 'attaching nipples l4jand l15. The pipe -112 is -the fluid discharge pipethrough whichthereservoir is drained, and- 16, in Fig. Lindicates the'usual rubber pipe onnipple14 leadingdown'tothe Working level. The .topror mouth of pipe l2ter, minates'at the bottom vof the-'reservoir -1 just above the stopper, with relation to which latter both pipes are, of course, sealed. 'The air -pipel extends asclosely: asv possible to the top wallof the receptacle, as-the intention is to have-it discharge above the level of the containedbody of fluid, for which purpose I fit this upper-end with ayeilding nozzle ortelescopicextensionl?.

`This consists of `a sleeve slidable onthe-tube, which latter is slottedat 18I to accommodate-a transverse pin 19 driven through the sleeve which actsy as -a guide kand stop. -A threaded "cap 20 at the lower end of the sleeve furnishes an airl.,

tight glandfor the sliding connection, while a coiled spring 21 interposed between the upperend of the tube and the partially closed upper -end of the sleeve has a tendency to project' the latter to the fullest extent andhold it in contact with the top wall of the reservoinas shown.V `This contact will thus be; maintained even though the position of the stopper'or'the 'depth of the receptacle may vary within reasonable limits in different assemblies.v An endA orifice -2-2 invthe extension 17 leads to lateral channels 23that open at the .sides and vent the air from the tube regardless of the impingem'ent against the top wall. The lower end ofi tube 13' within-the cavity of the stopper is provided with two openings 24 and 25 at relatively high points with respect to the air space in the stopper, which openings are sealed from each other within the tube by baffles 26, the purposes of which will now immediately appear.

In operation, the reservoir is filled in the ordinary manner of a jug or bottle through the neck and the stopper 9 with its accompanying gasket 8 wedged into place. As just described, the telescoping end of the tube 13 will extend the full height of the receptacle and make contact with the wall 3. Of course, the tube 13 will also fill with liquid, which enters through the lateral ports or channels 23, and when the reservoir is inverted to the operative position illustrated in the drawings the column of liquid so trapped would have a tendency to and ordinarily does, in known devices, run out of the air intake nozzle 15. With my invention, however, and in the present instance, no such action can occur, because the said column is stopped by the upper baiiie 26 and drains into the hollow stopper or trap 1l through opening 24. The capacity of the trap is greater than that of the tube 13 so that this charge of liquid lies in a body, indicated at 27 in Fig, 5, with its surface level below both apertures 24 and 25. Therefore, as the fluid is drawn out through pipe 12 at nozzle 14, air at atmospheric pressure is driven in to replace it through nozzle 15 taking a course through opening 25 in tube 13 to the air space preserved within the stopper and thence through opening 24 to rise in the tube and expel itself through ports 23.

Another advantage of the extensible tube 13 rising to the extreme top of the reservoir is that upon inverting the filled bottle an amount of fluid equal to the capacity of the tube 13 only requires being drained and provided for, whereas, if the air tube merely approximated the height of the reservoir and its top terminated short of the top wall 3, as is common in prior devices, not only the column of uid in the tube but all of the main body lying above it would have to be drained before the tube could function as an air injector. In ordinary use, upon inverting the reservoir after filling, the main body of the fluid comes to a level approximating that indicated by the dash lines 28 in Figs. 4 and 5. When the reservoir is taken down after use and rested upon its end 3, the body of liquid 27 trapped in the stopper will. reversely, drain back through the air tube and rejoin the main body.

It is desirable that a dependable locking means be provided for securely maintaining the stonper in place in a fluid-tight manner. particularly as when a gravity feed is inadequate or there is no place to hang the reservoir at a proper elevation a pump is used to force air under pressure through the pipe 13. In the present instance` I have illustrated for this purpose an attachment comprising a two-piece clamp 29 that is tightened about the neck '7 by means of draw screws 30 and to one half of which is pivoted at 3l a link 32 in turn'pivoted at its opposite end at 33 t-o a lever34 spanning the cap 10 of tlie stopper. It carries an adjustable presser foot 35 engaging the cap between the nipples 14 and 15. Its free end is inclined and provided with a series of serrations or teeth 36 to be adjustably engaged with a wedging action by a latch arm 3'7 through a slot 38 in which the arm extends, the latch arm being pivoted tothe other half of the clamp 29 at 39. Once engaged, the lock is tightened and the rubber gasket 8 compressed tc an adequate degree by pinching together nger pieces and el on the latch and the locking lever, respectively.
